Where to login Google music

The upmpdcli and gmusicapi code is open-source. You can post a pull request to JFDockes (Mr. Upmpdcli) to upgrade his code to use api.oauth_login() and include the extra credentials in upmpdcli.conf. Once this is committed, Tim can modify the moOde UPnP Config page and database to include those credentials too. 

I've heard back from the dev of upmpdcli, and said " I am quite willing to fix this, but I am a bit swamped. Hopefully I'll be able to get into it in the next few days." 

So there is that. I'll continue to tinker on my machine and see if I can get some headway!
